Anyone with access to the MLS can create a "Prospect" email which will notify you when a listing matching your criteria is entered into the MLS. There are several different MLS organizations in Colorado, but they will all report. You can sign up for these type of generic programs by visiting any broker's website, however, those programs are not as powerful as the ones the brokers can access directly. Call one of us. We are all hungry for the business!
Some things we can do that you can't: Price per square foot searches; acres; horse property; school district; map searches etc.
My website: http://www.GrantsHouses.com
has the same "automated search" as others, but it is weak in comparison with the searches we can perform directly through MLS prospecting tools.
